Python2 to Python3

To make HasyUtils compliant with Python2 and Python3, these changes had to be done, see below. The additions made by Pablo Bereciartua Perez are acknowledged.

                                   sys.stdout.flush()

 exec is a statement            -> exec() is a function, does not change local variables
                                   workaround, e.g. (from VmExecutor.py): 
                                     nameSpace = {}
                                     exec( "from veryTrivial import VM", nameSpace)
                                     self.vm = nameSpace[ 'VM']()
